GAS-PRODUCER.

Specification of Letters Patent.

Application filed December 30,1905. Serial No. 293.888.

T0 @ZZ whom, t may concern:

Be it known that I, WILLIAM R. MILLER, a citizen of the United States,residing at Pittsburg, in the county of Allegheny and State ofPennsylvania, have invented certain new and useful Improvements inGas-Producers, of which the following is a specification, referencebeing had therein to the accompanying drawing, forming part of thespecification, in which- Figure 1 is a vertical sectional view of myimproved gas-producer. Fig. 2 is a horizontal sectional view on the lineII II of Fig. 1. Fig. 3 is an enlarged horizontal sectional view on theline'III III of Fig. 1. Fig. 4 isa vertical sectional view on the lineIV IV of Fig. 3.

My invention refers to improvements in gas-producers, more particularlythe class of water-sealed gas-producers, and relates particularly to theconstruction of the air and steam supplying wind-box. In producers ofthis class it is desirable to provide a fuel-supporting air-supplyingstructure so arranged as to uniformly distribute the steam and air blastthrough the whole area of the fuel-bed, while providing for freedownward travel of the fuel-ash into the pan during combustion.

The producer 2, as shown in the drawings, is cylindrical incross-section, provided with the usual charging-hopper 3 and havingsuitable feeding mechanism and a gas-outlet opening 4.

5 is the water-seal basin, into which the ashes are deposited and fromwhich they are removed from time to time, the entire upper portion ofthe producer being supported above said basin by means of any suitablesupporting structure, as posts 6.

My improvement consists of a concentrically-located hollow ringconstituting a windbox, preferably triangular in cross-section throughone side, providing the upper outwardly and inwardly sloping faces 7 8,oppositely disposed and so arranged that the ash, &c., will passdownwardly and to the outside and inside of the wind box, respectively,due to such inclined faces. As shown in Fig. 2, the box is so arrangedas to the cross area of the interior of the producer that it willdistribute the air to the fuel from the inside and outside of thewind-box in a very thorough and efficient manner. The wind-box ispreferably composed of a plurality of sections bolted together by meansof flanges 9 extending across their lower portions, the upper, outer,and inner slanting walls 7 and 8 having interlocking joints, asindicated at 10, so that the entire series of sections are rigidly andtightly connected together. Each section is provided at the lowerportion of the slanting walls with series of air-supply ports 11 12 atthe inside and outside, respectively, and preferably just above thelevel of the base, the interior hollow cavity 13 preferably -extendingcontinuously throughout the circular interior. The entire wind-box issupported upon suitably-located standards 14, which may conveniently bemade of hollow pipe, and for the purpose of supplying air and steamunder pressure to the interior of the box two of said pipe-supports 14are connected with supply-pipes 15, communicating with a blower or anysuitable air and steam supply apparatus. The supply of air and steamthrough these pipes to the wind-box is controlled so that the gas-makercan force more or less air to the grate, depending .on the nature of thefuel or the condition of the gas required. As thus constructed theentire apparatus is very strong and substantial and is capable ofdistributing a copious supply of air and steam to all portions of thefuel, contributing to -very even combustion and greatly facilitating theoperation. The device is simple and economical in construction, will notreadily burn out, and may be easily and quickly renewed as to some orall of its sections.

It will be understood that with producers of greater diameter aplurality of concentric circular boxes may be utilized or that withproducers of oval, square, or other form the boxes may be made tocorrespond, and all such changes or modifications or others .which maybe made within the province of the skilled mechanic are understood to beineluded within the scope of the following claims.

What I claim is* 1. A wind-box for gas-producers consisting of a hollowring having an interior clearance-space, the surrounding hollow ring orIOO boX having outer and inner downwardly-diverging sloping wallsprovided with perforating air-supply openings, and means for furnishinga volume of air to the interior of the hollow ring, substantially as setforth.

2. A wind-box for gas-producers consisting of a hollow ring' having aninterior clearance-space, the surrounding hollow ring or box havingouter and inner downwardly-diverging sloping walls and a horizontallower closing-wall, said sloping walls having erforating air-supp@Topenings, substantia lv as set forth.

3. A wind-box for gas-producers consisting of a hollow ring having aninterior clearance-space, the surrounding hollow ring or box having'outer and inner downwardly-diverging sloping` walls and a horizontallower closing-wall, said sloping walls having perforating air-supplyopenings located immediately above said lower closing-wall,substantially as set forth.

4L. A wind-box for gas-producers consisting of a circularly-arrangedseries of connected hollow sections surrounding an interiorclearance-space, said sections having' outer and innerdownwardly-diverging sloping perforated walls arranged to deliver theburden to the outer and inner areas adjacent to the box, with means forsupplying a blast of air to the interior of the box, suhstantialh7 asset forth.

5. A wind-box .for gas-producers consisting of a hollow circular ring,the body portion of said ring consisting of a continuoustriangular-shaped boxY having outer and inner downwardly-divergingsloping sides arranged to deliver the burden to the outer and inneradjacent areas and a flat horizontal bottoni, said sloping sides being`provided with aircirculation openings, with means for supplying a blastof air to the interior, substantiall)v as set forth.

(i. The combination with a gas-prodneer chamber, of aconcentrically-arranged hollow ring located in the middleI portion ofthe producer and surrounding' an interior clearancespace, the bodyportion of said ring comprising a continuous hollow b ox havin g outerand inner downwardly-diverging sloping walls provided withair-circulation openings and a closing bottom, with means for supplyinga volume of air to the interior oi' the box, substantiallyv as setforth.
